Abstract
The effectiveness of CH3Br against Lepidosaphes camelliae and Fiorinia theae was studied at temps. ranging from 60 to 110[degree] F and with dosages ranging from 0.5 to 4 lb. per 1000 cu. ft. in gas-tight, iso-thermal chambers. Mathematical relationships were established for the requirements for a perfect kill of these scale insects and for tolerance limits of the plants. Equations and nomographs are given. The margin of safety to plants was sufficient to permit practical fumigation of camellias and azaleas. Fumigation schedules recommended for commercial treatment of plants were, 3 lb. for 3 hrs. at 60[degree] F, 2 lb. for 3.5 hrs. at 70[degree] F, 2 lb. for 2.5 hrs. at 80[degree] F, and 2 lb. for 1.5 hrs. at 90[degree] F.This publication has 2 references indexed in Scilit:
